Hi Chandan Kumar,

 

Are you looking to find out how many vCPUs you can assign to VMs on a node with that hardware?

If you look at the processor specs you will see:

Performance Specifications

  • # of Cores 10 < < < This is number of vCPU you can assign without hyperthreading
  • # of Threads 20 < < < This is number of vCPU you can assign with hyperthreading

In terms of how many vCPU can be assigned to a VM, the short answer is all of them but it is likely to cause performance issues. Take a look at this Number of vCPUs vs Number of Cores (UVMs, NUMA and CVMs) and also research on NUMA to understand the concept if you are not yet familiar with it.

Let me know if that is what you were after, or if there are further questions.
